Title: Evaluation of weighted regression and sample size in developing a taper model for loblolly pine

Author: Cormier, Kenneth L.; Reich, Robin M.; Czaplewski, Raymond L. Ph.D.; Bechtold, William A.;

Date: 1992

Source: Forest Ecology and Management. 53: 65-76.

Publication Series: Scientific Journal (JRNL)

Description: A stem profile model, fit using pseudo-likelihood weighted regression, was used to estimate merchantable volume of loblolly pine (Pinus taeda L.) in the southeast. The weighted regression increased model fit marginally, but did not substantially increase model performance. In all cases, the unweighted regression models performed as well as the weighted regression models, even for very small sample sizes.
